What can we do with oscillators?

An oscillator is used to generate a repetitive and periodic waveform of desired shape, frequency, and amplitude and you will find one in practically every electronic apparatus. It is either used to drive a load or to drive other circuits. Listed below are characteristic shapes of some oscillators.

Some signals are combined or mixed together to alter the shape and characteristics output to achieved a particular purpose.

Different types of oscillators find useful application in the following areas but not limited to these:
